Samsung has started seeding the October 2025 security update for the Galaxy Z Fold 7 and Galaxy Z Flip 7 devices. This crucial update includes a total of 34 fixes for vulnerabilities categorized as “high” and “moderate” severity levels, aimed at enhancing device security and performance.
The rollout has begun in Korea and is expected to reach other regions soon. Although the One UI 8-based update is arriving a bit behind schedule, it brings important security enhancements that Samsung foldable owners should not overlook.
### What’s Included in the October 2025 Security Update?
The update addresses 34 security vulnerabilities in total. Fourteen of these patches come from Google’s Android Security Bulletin and carry a “high” severity level. In addition, there are 20 fixes specifically targeting security issues found on Samsung devices, which range from high to moderate severity. Some of these fixes have not been publicly disclosed yet, highlighting the importance of updating your device promptly.
### Update Details and Availability
– **Galaxy Z Fold 7:** The update file size is approximately 535MB, with firmware version F966NKSS5AYJ3.
– **Galaxy Z Flip 7:** The update is slightly smaller at around 431MB, with firmware version F766NKSS5AYJ3.
So far, the update has been officially confirmed only for users in Korea. However, Galaxy Z Fold 7 and Galaxy Z Flip 7 owners in other regions should expect to receive the security patch within the next few days.
### Additional Information
The update rollout was first spotted by Tarun Vats on X (formerly Twitter) and later confirmed on Samsung’s community forums in Korea.
Notably, the October 2025 security patch arrived later than usual for Samsung foldable devices, with the rollout starting on Thursday, October 23. Prior to this, the Galaxy S25 series was among the first to receive the October security update as part of the One UI 8 rollout earlier this month.
### Conclusion
Given the range of vulnerabilities addressed in this substantial update, it is strongly recommended that Galaxy Z Fold 7 and Galaxy Z Flip 7 users install the October 2025 security patch as soon as it becomes available in their region to ensure optimal device security and performance.
